## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Defense and Space S.A. (formerly known as Construcciones Aeronauticas, S.A.) Model CN-235, CN-235-200, and CN-235-300 airplanes. This proposed AD was prompted by a torn bulkhead seal found jamming the nose landing gear (NLG) emergency cable pulley. Due to the similarity of design, the main landing gear (MLG) emergency cable pulley could be exposed to the same failure mode. This proposed AD would require repetitive inspections and corrective actions for damage of affected bulkhead seals and retainer rings, and repetitive replacement of affected parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
